An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-7507 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.keycloak:keycloak-services (Maven): affected all versions; fixed in 26.6.2\n- org.keycloak:keycloak-services (Maven): affected all versions; fixed in 26.6.2\n- keycloak (Bitnami): affected from 26.4.0; fixed in 26.4.12\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-7507/ (Markdown: https://insights.sbomify.com/CVE-2026-7507/index.md)","id":"CVE-2026-7507","markdown":"https://insights.sbomify.com/CVE-2026-7507/index.md","name":"CVE-2026-7507","record":{"aliases":["BIT-keycloak-2026-7507","ECHO-bd3c-e7a2-8a3a","GHSA-hf67-5vvq-fm3r","MINI-29jr-5rgh-pvr3","MINI-55g3-r6c6-8qwp"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Keycloak identity server","requires_auth":"none","summary":"An attacker can hijack user sessions via a crafted link in Keycloak's login flow, leading to complete account takeover including admin privileges.","user_interaction":"required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"build_of_keycloak","vendor":"redhat"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-290","name":"Authentication Bypass by Spoofing"}],"description":"A session fixation vulnerability was found in Keycloak's login-actions endpoints. An unauthenticated attacker could exploit this flaw by pre-creating an authentication session and tricking a victim into visiting a maliciously crafted link. By leveraging the /login-actions/restart endpoint—which processes session handles without adequate CSRF protection or cookie ownership validation—an attacker can reset the authentication flow state. This causes Single Sign-On (SSO) to authenticate the victim transparently upon clicking the link, allowing the attacker to hijack the required-action form without needing the victim's credentials. A successful exploit could lead to complete account takeover, including highly privileged administrative accounts.","ecosystems":["Bitnami","Maven"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Org.keycloak/keycloak-services: session fixation in oidc login flow that can lead to account takeover","id":"CVE-2026-7507","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"redhat:build_of_keycloak","products":["redhat:build_of_keycloak"],"type":"auth_bypass","year":"2026"},"n_packages":3,"n_references":11,"next":{"headline":"Bootstrap CMS Page Creation show.blade.php code injection","id":"CVE-2026-7508"},"packages":[{"ecosystem":"Bitnami","fixed":["26.4.12"],"introduced":["26.4.0"],"last_affected":[],"package":"keycloak","purl":"pkg:bitnami/keycloak","source":"BIT-keycloak-2026-7507"},{"ecosystem":"Maven","fixed":["26.6.2"],"introduced":["0"],"last_affected":[],"package":"org.keycloak:keycloak-services","purl":null,"source":"GHSA-hf67-5vvq-fm3r"},{"ecosystem":"Maven","fixed":["26.6.2"],"introduced":["0"],"last_affected":[],"package":"org.keycloak:keycloak-services","purl":"pkg:maven/org.keycloak/keycloak-services","source":"GHSA-hf67-5vvq-fm3r"}],"prev":{"headline":"SourceCodester Hotel Management System check sql injection","id":"CVE-2026-7506"},"products":["RHEL-8 based Middleware Containers","Red Hat Single Sign-On 7.6 for RHEL 7","Red Hat Single Sign-On 7.6 for RHEL 8","Red Hat Single Sign-On 7.6 for RHEL 9","Red Hat Single Sign-On 7.6.13","Red Hat build of Keycloak 26.2","Red Hat build of Keycloak 26.2.16","Red Hat build of Keycloak 26.4","Red Hat build of Keycloak 26.4.12"],"published":"2026-05-19","related":[{"cvss_score":8.8,"headline":"Keycloak-services: keycloak-services: dcr protocol mapper type-swap policy bypass allows privilege escalation","id":"CVE-2026-15572","kev_date_added":null,"published":"2026-08-05"},{"cvss_score":8.8,"headline":"Keycloak SAML Broken has Authentication Bypass by Primary Weakness","id":"CVE-2026-3047","kev_date_added":null,"published":"2026-03-05"},{"cvss_score":8.1,"headline":"Keycloak-services: keycloak-services: authorization bypass via unnormalized uri matching in pathmatcher","id":"CVE-2026-15573","kev_date_added":null,"published":"2026-08-05"},{"cvss_score":8.1,"headline":"Keycloak-services: keycloak-services: default dcr policy allows role forgery via user property mappers","id":"CVE-2026-16102","kev_date_added":null,"published":"2026-08-05"},{"cvss_score":8.1,"headline":"Org.keycloak/keycloak-quarkus-server: keycloak: unauthorized access via jwt authorization grant with disabled users","id":"CVE-2026-1609","kev_date_added":null,"published":"2026-07-16"},{"cvss_score":8.1,"headline":"Org.keycloak:keycloak-services: keycloak: authentication bypass via jwt algorithm confusion","id":"CVE-2026-11800","kev_date_added":null,"published":"2026-06-25"},{"cvss_score":8.1,"headline":"Keycloak-policy-enforcer: keycloak policy enforcer: authorization bypass via incorrect uri comparison","id":"CVE-2026-9800","kev_date_added":null,"published":"2026-06-25"}],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-06","vendors":["Red Hat"]},"summary":"An attacker can hijack user sessions via a crafted link in Keycloak's login flow, leading to complete account takeover including admin privileges.","url":"https://insights.sbomify.com/CVE-2026-7507/"}
